Statistical analysis of measured radio channels for future generation mobile communication systems

Measurements of radio channels with 100 MHz bandwidth at 5.25 GHz have been performed in both indoor and outdoor environments. The statistical properties of the tap amplitudes have been analyzed together with general channel characteristics, such as path loss, delay spread and coherence bandwidth. With 100 MHz bandwidth, it was found that the average power delay profile consists of several delay time clusters. The tap amplitudes follow Rice or Nakagami statistics for some taps in the beginning of the clusters while the other taps are close to Rayleigh fading. An approach to model the average power delay profile and the frequency correlation is also presented.
